CARPET-CLEANER.

Specification of Letters Patent.

Patented Sept. i9, 191.6.

Application filed .Tan'aary4 13, 1913. Serial No. 741,628.

To all whom it 'may concern Be it known that I, FRANK J. QUIs'i, a citizen of the United States, residing at lVin-cester, in the county of lVorcester and State, of Massachusetts, have invented a new and useful Carpet-Cleaner,.of Iwhich the following is a specification.

This invention relates to. a carpet cleaner. The principal objects thereof are to provide a simplified and practically operating combination between an ordinary pneumatic carpet cleaner and a rotary'brush carpetl sweeper.

It has been found in practice that the brush carpet sweepers and the pneumatic carpet cleaners are to a certain degree complementary to each-other, each one being capable of accomplishing certain results not accomplished in a high degree by the other. l am aware of the fact that several attempts have been made to combine the two devices, but so far as l am aware they have generally7 involved either the placing of the rotary brush in the nozzle of the pneumatic device, in which case the pneumatic device does nothing except to take up and carry awaythe air and dust` stirred up by the brush, or they have lnvolved complicated mechanism, costing to build at least as m-uch as the combined cost of a pneumatic and a brush cleaner. This invention is made for the purpose of combining these elements in a new'way so as to avoid these objections, and to get the results ol' both the pneumaticy cleaner and thc sweeper. and also to provide for the operation of either one of lhein independently of the other without the eniploynient of complicated mechanism for making the change.

'l`he invention also involves improvements in details ol construction as will appear hereinafter.

Reference is to be had to the accoinlnmying drawings in which- Figure 1 isa side elevation of a pneumatic carpet cleaner ot' a type such as that represented in the patent to nl vsell' and Malcolm Vlt will be seen that l have/shown the invention as applied to a pneumatic carpet cleaner comprising a casing 10, wheels or roller supports ll near one end fosupporting that end of the easing, said wheels being mounted on a shaft l2 and having cranks 13 for operating arms or pitmen 14E which are connected with the suction creating devices or vbellows 15. These bellows take air froma` chamber 16 in which is located a dust bag 1T or the like, provided with a nozzle 18 at the outer end secured in this instanceby screws and thumb nuts 19. A roller 20 is provided having an adjusting screw 21 for two purposes, first, to adjust the nozzle into proper relation with the surface over which it is traveling, and second, to raise it entirely out of contactl with that surface when desired -in order to render this' part of the apparatus inoperative. It will be seen that the wheels, as has been thel case with this and that the(v are provided with rubber tires or rims. Therefore, as they pass ove-r the Hoor the.'Y are turned by the motion of the casing along the floor or carpet so as to operate the bellows.

As so far described, the instrument is one which can be usedsas a pneumatic cleaner without further attachments and it is a complete pneumatic cleaner in-itself. For the purpose of adding the positive sweeping feature, a very sim-ple arrangement is provided. rl`he end of the casing beyond the wheels is discontinued below the surface 26 and on the end of the casing is fifed an auxiliary casing 2T of-sinall size., This is shown as having an upwardly extending llange 2.5 provided with elongated openings 2S) through which fastening screws or bolts 25() are passed. so that this. casing can be arranged in any desired adjusted position. The top ot' the auxiliary casing extends `downwardly at a slant and it also has a projecting part fl extending back under the bearings ol the shaft 12. Mounted on the outside ol this casing are a pair'ol" pivoted brackets L provided with adjustable bearings 321 for the ends of a brush sha l't J-l. This shal'l has a c vlimlrical brush 35 thereon. and it is also provided with a pair oll wheels or rollers 3G outside the auxiliary casing. in this instance. (ln the top ol' the auxiliary casing in the center lof the. nozzle is a spring 3T having two dev sion` 38 the brackets, brush, and shaft are elevated so as to bring the brush out of contact with the oor, and at the same time .the wheels 36 out of contact with the tires on lthe wheels 11.l This renders thebrush inoperative both because it stops rotating and becausel it is out of contact with the floor.

It will be remembered that the pneumatic cleaner is provided with a dust collecting device 17 near the nozzle, and in asimilar way lthe brush cleaner is provided with dust collecting devices on each side thereof. One of these is shown as a pivoted pan 4o located just at the end of the auxiliary casing, and having an operating arm 46 for swinging it down againstthe action of a spring 47 to permit of its being emptied. The other one is also in the form of a an 48 ivoted O11 the projections 31 an provided with springs 49 for holding it in horizontal position. It is provided also with an extend ing lip .5() which projects beyond the shaft 12 and engages the bottom of the main casing 10, being provided with an operating surfaceover which the device moves. It isarm 51 or other device for forcing it open. In this way it will be seen that this pan not only catches the dust from that side of the brush but also catches any dust that can collect inside of that end of the casing of the pneumatic cleaner and fall down through the space above the shaft 12.

The operation of the device is very simple. iV hen the rod 40 is in the notch 39 and the wheel 2O is adjusted to such a position that the nozzle 18 can engage the floor or carpet, the motion of the casing over theI same will :result in cleaning the surface both pneumaticallyand by the brush. In this way both papers and threads can be removed from the surface and the dust 'also can be drawn up from the bottom of the nap, and in fact even from the underside of the carpet, thus securing a sure, thorough, and. eifective cleaning action. However, when it is desired to dispense with the use of the brush the only thing necessary is to swingthe rod l() over into the catch 38 and when it` is desired to use the brush alone it is `simply necessary to have the rod in the notch 39 and adjust the screw 21 untilthe nozzle is out. of edective contact with the to be observed lthatin all three cases Athe wheels 11 operate the device in an exceedingly simple manner and that no parts have to be removed and no complicated mechanism has to be adjusted. In addition to this it Will be understoodthat the auxiliary casing With its brush and dust collectors can be removed from the. carpet sweeper without alfecting the pneumatic action thereof. Moreover, such an auxiliary casing with or without obvious modifications can be applied to any pneumatic cleaner of the roper size and type without modifying 1t in any way except to saw olf a small portion of the casing below the surface 26 or to leave that out in the manufacture of the device. In this way a partyhaving a pneumatic cleaner can add the brush attachment at very small' expense, and a party proposing to buy one can get the advantage of thebrush sweeper at Very low additional cost.

' Although I have illustrated and described onlya single embodiment of the invention,r

I. am aware of the iact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but

What I do claim is :4-
